WordPress houses lots of different types of content and they are divided into something called Post Types. A single item is called a post however this is also the name of a standard post type called posts.

The default post types that are always included within a WordPress installation unless otherwise removed are:
– Posts
– Pages
– Attachments
– Revisions
– Navigation Menus
– Custom CSS
– Changeset
